ROBERT A. GALLY, OF CINCINNATI, OHIO, ASSIGNOR TO THE BALDWIN COMPANY,OF CINCINNATI, OHIO.

MUSIC-PLAYER VALVE.

. citizen of the United States, residing at Cincinnati, in the county ofHamilton, State of Ohio, have invented certain new and usefulImprovements in Music-Player Valves, of which the following is aspecification.

The Object of my invention is to obviate various noises common toprevious devices of this nature and make easy the regulation of thevalves to the pneumatics that actuate said valves, and to preventdisturbance or injury to the valves or the striker pneumatics byaccidental collapse of said strikers i from an outside blow of aworkmans hand.

In the drawings Figure 1 is an end view of a valve chest in section witha striker pneumatic attached, and Fig. 2 a front view of said chest withparts in section taken at A and B of Fig. 1.

The valve action now shown comprises a pouch rail 1, valve rail 2 andvalve-cap 3, a striker pneumatic 1 being attached to said rails 1 and 2,preferably by leather or similar split joints 5 and 6 glued to bothstriker and rails, to allow removal of striker for repairs by thepulling apart of the leather without damage to the wood of either board11 of striker 4:, or of rails 1 and 2.

The valve seats 16, 17 usually of eyelet form, may be of any suitablematerial, a noncorrosive substance preferable, as hard rubber or thelike, and of a nature that will not warp from a true face. To avoiddanger of such seats loosening from their valve boards as 2 and 3, andconsequent leakage, and as safeguard against the shrinkage of the woodof said boards cracking a hard rubber or compo seat, or the splitting ofthe board from its shrinkage strain on the seats or eyelets, the hole inthe'valve board is made loose to the valve seat, a gasket 18, 19, ofyielding material, as leather, is made with a central hole to fit snuglyover the stem or hub of the seat or eyelet, with the outer part of saidgasket extending outward and sealed to the valve board. Such a joint isabsolutely safe against leakage or other trouble.

Regulating of valves20 and 21 with respect to each other and to thefollower 22 attached to pouch 23, is made easy by having Specificationof Letters Patent.

Patented July 28, 1914:.

Divided and this application filed February the valve rod 24 placedloosely in a hole 25 of follower 22, so that rod 24 may be withdrawnfrom hole 25 and together with its assembled valves on it, be removedfrom the valve action for regulating or cleaning. A regulating button 26just to the rear of valve 20 is movable lengthwise of valve rod 2% on athreaded portion of the rod, and adusts follower 22 and pouch 23 tovalve 20 when latter is seated, and is easily adjusted when rod 24 andits valves are removed without the risk of loosening the follower fromthe pouch as when turning a valve rod that is screwed into its follower.To use a spring as 27 to aid the return of valves 20 and 21 and rod 2 1,and tight seating of valve 20, and yet avoid a shoulder on rod 24 thatwould interfere with the removal of the valves from the rod, a removablesleeve 28 is slid freely on to rod 2 1, with the rear end of the sleeveagainst the valve parts, and its forward end against the guide spring 27which presses back the sleeve against the valve parts.

The rturn vent 29 is placed in the follower button 22 which is attachedto pouch 23, this vent 29 being opposite to the valve port or hole 30,so that the vent may be examined, regulated or cleaned through saidvalve hole 30 when the valve is removed.

The prevention of over-quick inward flow of outside air to a pneumatic4: is obtained by a felt 33 or similar porous material placed across theouter port 34, most conveniently and neatly in a counterbored hole orrecess 35 in face of valve cap 3, the hole 35 being preferably largerthan port 34, to allow use of porous or air retarding material of ordinary thickness instead of an extremely thin material required for thesmaller hole 34.

The air flow retarding of the outer port not only quiets the air rushnoise through outer port 34, but prevents racing and consequent poundingor snapping noises of striker pneumatic 4: on quickly repeatingoperation, and reduces the tendency of valve.

20 to make a pounding noise at finish of its return action.

Many of the parts shown herein are for illustration only, such partsbeing also shown, and many of them claimed, in my original application#7 30,635, filed November l1th, 1912, from which this application is adivision.

What I claim as my invention, is

1. A music player valve action having a valve board, a valve seat havinga main part and a flanged head, and a gasket of yielding material havinga part thereof snugly surrounding the main part of said valve seat andbetween its said head and board, the face of the gasket being attachedto said valve board.

2. A music player valve action having a valve board, a valve seat havinga main part and a flanged head, and a gasket of yielding material with ahole therein snugly surrounding the main part of said valve seat, theface of the gasket being attached to said valve board, and that part ofthe gasket adjacent its hole lying between the under part of said flangeand the part of the board immediately under said flange.

3. A music player valve action having a valve board with a hole, a valveseat having a main part and a flanged head, with the main part looselyWithin said hole, and its flanged head extended over said board aroundsaid hole, and a gasket of yielding material snugly surrounding the mainpart of said valve seat between the under part of the flange head andthe board, the gasket being attached to said valve board out side ofsaid hole.

4. A music player valve action having areciprocating motion valve and apneumatic to actuate same, a hole in a solid part of said pneumatic andopposite to said valve, and in axial alinement with said reciproeatingmotion and of greater length in that direction than said motion, a valverod having its inner end resting loosely in said hole and having thevalve mounted on said rod, said rod extended through said valve andbeing freely removable from said hole and the action together with saidvalve.

5. A music player valve action having a reciprocating motion valve and apneumatic to actuate same, a hole in a solid part of said pneumatic andopposite to said valve, and in axial alinement with said reciproeatingmotion and of greater length in that direction than said motion, a valverod having its inner end resting loosely in said hole and having thevalve mounted on said rod, and said rod extended through said valve,said rod extended into said hole a distance greater than. saidreciprocating motion.

6. A music player valve action having a reciprocating motion valve and apneumatic to actuate same, a straight hole in a solid part of saidpneumatic and opposite to said valve, and a valve rod having its innerend resting loosely in said hole and having the valve mounted on saidrod and said rod extended through said valve.

7. In a music player valve action havi a valve cap, a valve rod passingthrou g g said cap, and a valve on said rod rearward of said cap, asleeve freely mounted on said rod with its inner end against said valveand its outer end forward of said cap, and a spring forward of said capand against the outer end of said sleeve.
